A-pplicatonled September-14,1921, Serial No. 560,531. Renewed March 3,

My invention'has for its object to produce a simple and novel means for anchoring the inner end of a drawbar which must -be capable of swinging in a vertical plane and also in a horizontal plane.

The various features of novelty whereby v'my invention is characterized will hereinafter be pointedout .with particularity in the claims; but, Afor a fullunderstanding of 'lmy invention -fandotits object and advan- `-tages, reference may be had to the follow ing detailed description taken in connection vwith the laccompanying drawings7 wherein:

Referring to Figs. 1 to 4 of the drawings,

1 represents a plate adapted to'beA fastened to .theundertrame of airailway car. "The forwardportion of the plate has a depressed portion 2 providedwith a flattened bottom 3. The rear wall of.thedepressedportion is continued downwardly as indicated at e, and is then carried forwardly in the torni of a part 5 lying at some distance below and parallel with the flattened part 3. The jaw thus formed is stiffened and braced by means of two parallel webs 7 extending downwardly from the rear edge of the plate l and underneath the forwardly-projecting -withthe members 41- and. In the parts s .and the o rawbar may be Vas a vlocking means, to Tprevent accidental parte; the webs-being integr lly connected andv 5 are placed axially align d round holes 8 and 9 respectively, the hole 8 being larger in diameter than the hole S. rEhe members 3 and are stitlqened in the vicinity of the holes by means of annular' iianges 10 and 11 surrounding these respective holes. 12 is an anchoring pin whose largest diameter is no greater than the diameter of the upper hole 8 and which has at the lower end a reduced cylindrical part 13 which lits rotatably in the hole J; the up ier Vend of the pin 'l g rotatably in the hole 8.' Therefore the pin may be placed in position or removed by sin'iplylowering it'or raising i t' through the top ot the plate.

The drawbar 1liwhich is to be anchored to the plate has lat its rear Aend-a jaw 15 adaptedv to enter the space between the parts'l and 5 ot the linedy anchoring member or casting and embracethe anchoringpin. The anchoring pin andthe -j'aw are pivotv ally connected together by means of a transverse pin or pintle 16 v passing through the same; the pin or pintle 16 being fastened in any suitable way as, for example; by providing it at one end'with a head and plac ing acotter pin 17 through the other Yend.

The anchoring pin is preferably flattened on opposite sides'as indicated at 18 so as to afford 'comparatively'wide bearing surfaces= between the same and the .side to thc jaw.

l't will be'seen that the drawbar may be swung in a horizontal plane through a large angle by causing the anchoring pin to turn with it. The drawbanmay also be swung up and down in a vertical plane about the hinge pin 16.' Betere the anchoring pin is pinned to the `inner end of the drawbar Vit may be moved into and` out ot position, but, atter the connection between the anchoring pin and the drawbar has been made, Vthe drawbar prevent-s the anchoring` pin from being lifted out et its bearings. Therefore the attaclnnent between the anchoring pin said to serve also displacement of the anchoring pin. l have therefore produced an anchoring attachment for the inner end of the drawbar which consiste of a few simple elements which may readily be assembled and disconnected from each other, and which are strong and durable so as to insure long life. f

In Figs. 5 to 8 inclusive I have shown a somewhat different form of my invention. The anchoring casting is the same as that heretofore described, but the anchoring pin 2O has a somewhat different liorm than the pin 12. rlhe upper end of the pin 2O has a portion 2l of reduced diameter and this, instead ot litting into the hole or bearing 8, tits rotatably in a sleeve 22 arranged within the hole or bearing 8. rlhe pin and the sleeve are held against displacement by means or a cover plate 23 lying above the same, preferably upon and making` a tight iit with the annular A[lange l0; the cover plate being fastened in position by means ot suitable bolts or stuos Q/l. lt will be seen that the cover plate not only holds the anchoring pin against displacement.l both when the drawbar is attached to the anchoring pin and when the drawbar is disconnected, but also acts as a cover or shield to prevent the entrance of water and dirt into the bearing 'for the upper end ot the pin.

In Figs. 9 to lil inclusive l have shown a still 'further modification in which the anchoring casting is made in two parts which must be separated from cach other in order to place the. anchoring pin L position or remove it. Theplate 25, corresl vnding to the plate l, has the depressed portion 2 provid ed with a fiat bottom 3. 1instead oit the integral underlying member 5, l have provided an auxiliary plate 26 which is attached to a downward bracket-like extension 2T eX- tending downwardly from the plate 25 in rear of and partly surrounding the depressed portion 2; the plate 26 being iastened to the bracket-like part by means ot a number of bolts 28. rPhe anchoring' pin 29, in this instance, has reduced upper and lower ends as indicated at 3() and 3l. if desired, the body or intermediate portion of the anchoring pin may be made square or rectangular'. rllhe holes 32 and 33 in the parts 3 and 26 respectively are made just large enough to receive the reduced ends BO and 33 of the anchoring pin. ln order to place the anchoring pin in position, the plate 2G must be detached, and Athis plate must also be detached before the anchoring pin can again be removed. lilowever, the drawbar may be fastened to the anchoring pin or disconnected therefrom without disturbingthe anchoring pin. llhile the vice just described may not be quite as simple as that disclosed in Figs. l to 1l, it is just as rugged and possesses what may sometimes be considered an advantage, namely the capacity of locking the anchoring pin nected to the lower end oit' against accidental displacement even after the drawbar has been disconnected.

While l have illustrated and described with particularity only a 'few preferred forms of my invention l do not desire to be limited to the exact details thus illustrated and described; but intend to cover all forms and arrangements which come within the terms employed in the definitions ot my invention constituting the appended claims.

l claim:

l. In combination, a flat plate having at the iront a tlatbottomed depressed portion, a bracket-like part'projecting downwardly from the rear por-ion oit the plate behind said depressed portion, and a' forwardly-em tending cantilever member at the lower end of said bracket-like part lying parallel with and below the bottom oia said depressed portion; a vertical anchor pin extending between and revolubly supported at its ends by the flat bottom of said depressed portion and said cantilever; and a drawbar hinged to said pin so as to be capable oi swinging vertically thereon.

ln combination, an anchor` member upper and lower elements spaced apart from each other, a vertical pin extendi Y between said elements and journaled at its upper end in said upper element, the lower end oit the pin being reduced in diameter and being fitted to rotate in a bearing in the lower element, the journal opening in the upper element being large enough to pern'iit the removal ot said pin through the same, a drawbar having a jaw embracing said vertical pin, and a transverse pivot pin passing through the members oi said jaw and said vertical pin, said jaw being of such a. depth that it approximately fills the space between the upper and lower elements ot said anchor member.

3. ln combination, atiat plate having at the iront a fiat-bottomed depressed portion, a downwardlyextending part in rear of said portion, a forwardly-extending member conthe downwardly-- intending part andv lying below and parallel with the flat bottom oit said depressed portion, a vertical anchor pin extending ben tween and rotatably supported by the attoresaid member and said depressed portion, a drawbar having a jaw embracing said vertical pin, and a transverse pivot pin pass ing through said jaw and said vertical pin,

ln testimony whereof, I sign this spediti-- cation.
